Virtual Server - Edimax ER-1088 User Manual

Virtual Server

This feature allows you to make Servers on your LAN accessible to Internet users. Normally, Internet
users would not be able to access a server on your LAN because:
•
Your Server's IP address is only valid on your LAN, not on the Internet.
•
Attempts to connect to devices on your LAN are blocked by the firewall in the Multi-WAN VPN Link
Balancer.
The "Virtual Server" feature solves these problems and allows Internet users to connect to your
servers, as illustrated below.
PC using FTP Server
(ftp://205.20.45.34)
PC using Web Server
(http://205.20.45.34)
Note that, in this illustration, both Internet users are connecting to the same IP Address but using
different protocols.
Connecting to the Virtual Server
Once configured, anyone on the Internet can connect to your Virtual Servers. They must use the
Multi-WAN VPN Link Balancer's Internet IP Address (the IP Address allocated by your ISP).
e.g.
http://205.20.45.34
ftp://205.20.45.34
•
To Internet users, all virtual Servers on your LAN have the same IP Address. This IP Address is
allocated by your ISP.
•
This address should be static, rather than dynamic, to make it easier for Internet users to connect
to your Servers. However, you can use the Dynamic DNS feature (explained later in this chapter)
to allow users to connect to your Virtual Servers using a URL, instead of an IP Address.
e.g.
205.20.45.34 (WAN)
Multi-WAN VPN Link Balancer
